I.Summary:
LR1151/3351 smart transducer sensor is small, hard, it is mainly used for measuring liquid, gas or steam differential pressure, pressure, liquid level and density, then convert them into 4 ~ 20 mA. DC signal output. Differential pressure transmitter including DP type (the base type), HP type (high static pressure) and DR type(differential pressure) of three types. The above three kinds of transducer combined with intelligent amplifier plate,can constitute a smart differential pressure transmitter, it through mutual communication with the hand operator that conform to the HART protocol, for set up and monitor.

II.Characteristic:
*Delicate design
*High precision, variety, wide measuring range, good stability
*Using two wire way to work
*Using solid circuit components, printed circuit board ,with a plug
*Unique structure design, firm,strong anti-seismic capability
*Range and zero level can be continuous adjustment in the external
*Positive transfer can reach to 500%, negative transfer can reach to 600%
*Through mutual communication with the hand operator that conform to the HART protocol
